The Kubernetes CSI plug-in implements the Container Storage Interface protocol, which enables containerized applications in Kubernetes clusters to use block storage. To effectively address the challenges of persistent storage, the PowerFlex system has a unique CSI plug-in. With the CSI plug-in for PowerFlex systems, customers can deliver persistent storage for container-based applications on premises, for both development and production scale.
The following figure depicts a general implementation of the CSI plug-in for PowerFlex systems:
